Accessories
AQB2002
Mounting kit for remote mounting with 1 m
copper capillary line, both ends prefabri-
cated ready for connection.
Thread adapters and terminal nuts made
of brass. Pressure connection with G1/8“
or G1/2“ outer threading.
Mounting instructions
Mounting instructions are enclosed with the differential pressure sensor.
The QBE63-DP... sensors can be connected directly with G
1
/8" or R
1
/8" screwed
fittings. Special precautions must be taken on site when mounting the sensors, to
ensure airtight screw connections.
• Use standard T-fittings or drill and de-bur measuring holes, each 5 mm diameter, for
the pressure tapping points (A).
• An isolating bypass (5) can be fitted to avoid overloading the pressure sensor on one
side while making adjustments.
• For inspection purposes, measuring circuits can be fitted with a measuring-T at the
sensor head.
Mounting for use with liquids:
• Always mount the sensor lower than the pressure measuring points
• Mount on a vibration-free surface
• Always evacuate the system

For remote mounting, the sensor can be operated together with the AQB pressure
mounting kit in ambient temperatures of up to 70 °C for medium temperatures of up to
180 °C. Care must be taken in this case to ensure that the cooling efficiency of the
copper pipe is not reduced by additional heat sources or by restrictions to the air circu-
lation.
